Step‑by‑Step Instructions for Crock Pot Green Bean Casserole
Step 1: Prepare the Crock Pot
Lightly spray the inside of your crock pot with nonstick cooking spray or line it with a slow cooker liner for easy cleanup. This ensures that your Crock Pot Green Bean Casserole won’t stick and will serve beautifully when it’s time to enjoy. Set your slow cooker aside while you prep the ingredients.
Step 2: Combine Ingredients
In a large mixing bowl, drain the cut green beans and add them to your prepared crock pot. In the same bowl, whisk together the cream of mushroom soup, milk, salt, black pepper, and onion powder until the mixture is smooth and well blended. Gently fold in half of the crispy French-fried onions, combining everything evenly before pouring the creamy mixture over the green beans in the crock pot.
Step 3: Cook the Casserole
Cover the crock pot and set it to cook on low for 2-3 hours or on high for 1 hour, depending on your schedule. Keep an eye on the casserole, as you want the green beans to be tender and fully coated in the creamy sauce. The aromas wafting from the slow cooker will signal when it’s nearly ready to serve—what a delicious preview!
Step 4: Finish and Serve
When your cooking time is complete and the green beans are tender, remove the lid and sprinkle the remaining French-fried onions generously on top of the casserole. Let it sit uncovered for a few minutes to let the topping crisp up a little. Then, dish out generous portions of your Crock Pot Green Bean Casserole and serve it warm alongside your favorite holiday dishes.
